In recent years, studies have shown that GABA has a certain therapeutic effect on acute lung injury (ALI), but its specific mechanism has not been fully elucidated. The study was designed to investigate the protective effect and mechanism of γ-aminobutyric acid (GABA) on ALI induced by lipopolysaccharide (LPS) in mice. ⋯ GABA can effectively alleviate ALI induced by LPS in mice, and its effect may be related to the upregulation of type B receptors.

STAT4 is a transcriptional regulator that has been reported to have oncogenic activities in various cancers. In our study, the posttranscriptional regulatory effect of miR-200a-3p on STAT4 and the prognostic significance of miR-200a-3p and STAT4 were evaluated in bladder cancer (BCa). ⋯ The miR-200a-3p/STAT4 signaling cascade plays an important role in the progression of BCa, which provides a new promising target for targeted BCa therapies.

The function of cytotoxic cells may be impacted by CD39 expression on CD8-positive T lymphocytes, leading to an imbalance in tumor immunity. ⋯ This research demonstrated the potential value of CD39 on CD8-positive T lymphocytes as a negative regulator in cancer immunotherapy.

The aim of this prospective trial was to evaluate the ovarian reserve with anti-Müllerian hormone (AMH), which is the best predictor of ovarian reserve, and perform histological analysis after exposure to cisplatin with a GnRH agonist or antagonist. ⋯ This is the first prospective randomized controlled study showing the protective effects of GnRH agonist and antagonist on ovarian reserve after cisplatin exposure in an animal model.

The most common cause of death in patients with amyotrophic lateral sclerosis (ALS) is respiratory failure, often in the period of 2-5 years, with a small percentage of patients surviving up to 10 years or more. The aim of the study was to evaluate the significance of pulmonary function tests in prediction of mortality and definition of indications for noninvasive mechanical ventilation (NIMV). ⋯ Our study points to the significance of timely application and early start of NIMV in patients with ALS as an important approach to defer functional impairment, which would mean that the criteria, in our country, for application of these devices must be changed, not only regarding the value of current functional diagnostic tests used in everyday practice in patients with ALS but also in regard to the introduction of new diagnostic tests, such as sniff nasal inspiratory pressure and/or polysomnographic testing.
